Force Law For Simple Harmonic Motion

Whenever a body is displaced a little from its equilibrium position(main position) a restoring force act on the body in the direction opposite to its displacement in order to bring the body back to its equilibrium position. This restoring force is proportional to the displacement, provided the displacement is small. If the body is left […]

Uniform Circular Motion and Simple Harmonic Motion (Geometrical Interpretation Of SHM)

We consider a particle P moving along a circle of radius A with uniform angular velocity ω. Let N be the foot of the perpendicular drawn from the point P to the diameter XX’. Then N is called the projection of P on the diameter XX’. As P moves along the circle from X to

Characteristics Of Simple Harmonic Motion

Some of the important parameters which define the characteristics of a simple harmonic motion are given below. (I) Displacement The displacement of a particle executing SHM at an instant is given by the distance of the particle from the mean position at that instant. The value of displacement as a continuous function of time can

Simple Harmonic Motion

A special type of periodic motion in which a particle moves to and fro repeatedly about a mean position under the influence of a restoring force is known as a simple harmonic motion (SHM). The restoring forces always directed toward the mean position and its magnitude at any instant is directly proportional to the displacement

Periodic and Oscillatory Motion

Periodic Motion Any motion that repeats itself over and over again at regular intervals of time is called periodic or harmonic motion. Example: (I) The motion of any planet around the sun in an elliptical orbit is periodic. (II) The motion of the moon around the earth is periodic. (III) The motion of the hands
